Geology Kitchen #9 - Plate Tectonics
This episode discusses the scientific theory of plate tectonics, in which the Earth’s crust is subdivided into a series of large and small tectonic plates. Convergent, divergent or transform boundaries are discussed and demonstrated with brittle graham crackers and icing to illustrate the motions of the plates at these boundaries. A second demonstration consisting of heating cream in a pan, representing convecting upper mantle, driving a relatively brittle layer of cocoa powder
Israeli, Hamas rockets hit schools
An Israeli strike on a UN school in Gaza that injured 30 people, most of them children, garnered criticism from the United Nations and even close ally, the U.S. Deborah Gembara reports.

21L.488 Contemporary Literature: Literature, Development, and Human Rights (MIT)
Central to our era is the gradual movement of all the world's regions toward a uniform standard of economic and political development. In this class we will read a variety of recent narratives that partake of, dissent from, or contribute to this story, ranging from novels and poems to World Bank and IMF statements and National Geographic reports. We will seek to understand the many motives and voices – sometimes congruent, sometimes clashing – that are currently engaged in producing
10.4 Summary The decibel (symbol dB) is a way of expressing a ratio. It is based on logarithms, and so adding decibels is equivalent to multiplying their corresponding ratios. Decibels can be used to express absolute values by referring them to a reference value. A common use of decibels is to express ratios of amplitudes. For instance, the amplification (or gain) of an amplifier can be expressed either as the ratio of the output and input amplitudes, or as a certain number of decibels. With a multi

3.016 Mathematics for Materials Scientists and Engineers (MIT)
This course covers the mathematical techniques necessary for understanding of materials science and engineering topics such as energetics, materials structure and symmetry, materials response to applied fields, mechanics and physics of solids and soft materials. The class uses examples from the materials science and engineering core courses (3.012 and 3.014) to introduce mathematical concepts and materials-related problem solving skills. Topics include linear algebra and orthonormal basis, eigen

1.1.1 About the course This course teaches on drawing and interpreting graphs. It has eight sections, each dealing between them with 4 different types of graph. You will need to draw some graphs, so make sure you have a flat surface to work on. You will also need to have centimetre graph paper and your calculator to hand as you study the material.
Section 3 is based on a video band, ‘Single-track minders’. This is split into four separate viewing sessions, each followed by an activity. You should expect
2.2 Converting units A great advantage of the metric system of units is that conversion between units within the system is particularly easy. For example, ‘£1 is worth 100p’ is converting one pound into pence. To convert pounds to pence, you multiply by 100. So £2 is 200p, and £2.63 is 263p. (Remember that to multiply by 100, you move the digits two places to the left in the place value table.) To convert from pence to pounds, you need to reverse this process, i.e. to divide by 100 (moving the

5.13.4 Pitches of notes produced by percussion instruments We have seen that none of the rectangular bar, the circular membrane and the circular plate have harmonically related natural frequencies. It may not surprise you to learn, therefore, that instruments containing these primary vibrators tend to produce notes that don't have a very well-defined sense of pitch. This is certainly true in the case of the cymbal, which has a circular plate as its primary vibrator. Whether a single cymbal is struck with a drumstick or two cymbals are crashed t

4.3.1 Pie charts A pie chart is a diagram in the form of a circle, with proportions of the circle clearly marked. A pie chart is a good method of representation if we wish to compare a part of a group with the whole group. It gives an immediate idea of the relative sizes of the shares. So, for example, it can be used to consider advertising income. It can also be used to look at, say, shares of market for different brands, or different types of sandwiches sold by a store.
